Posted 14 Aug 2020 Hello all, kinda lazy question, but I'll rather ask, before I'll went to deep into HMI scripting. Because of a design of CC link, there are RWr and RWw Is there any simpler solution for displaying value stored in PLC, while also letting HMI operator change the value and save it to PLC, than scriting in HMI? hope it makes sense to you thank you in advance Share this post Link to post Share on other sites

Posted 14 Aug 2020 Which HMI is it? Likely the connection manual for it would show how to access controller data. I don't think you are limited to the read and write words, i think there is messaging capability, but have never put an HMI on a field level network before, only serial and Ethernet.

Posted 17 Aug 2020 HMI should be on Ethernet, not a field level network. Makes life so much easier. Share this post Link to post Share on other sites
